To all 167mm it ma'fcomem:

Be it known that 1, PETER Bnuonns, a subject of the Emperor of Germany, residing at Aachen, Germany, have invented certain new and useful Improvements 1n Fee'dmg- Bottles for Children, of which the following is a full, clear, and exact specification.

The resent invention relates to a feeding bottle or children, which although allowing the entrance of air into the bottle yet effectively prevents the escape of same when in or out or use. This result is obtained by arranging the customary air conduits in the neck oi the bottle in such a manner, that. they end within a short distones from the bottle top, leaving a small smooth margin between said top and the upper ends of said conduits. \Vhen then the customary nipple is drawn over the bottle neck, the same will tightly fit 'over the smooth margin at the upper end of'the, bottles neck and prevent the escape of milk,

but at the same time will allow the free passage of air through the air conduit and over the small smooth margin, meanwhile the tight and elastic rubber nipple by the creation of a partial vacuum through the suction and the ressure of the atmosphere, is slightly lifte thus admitting 'air into the bottle.

In the accompanying drawing, 'Figure 1 is a side view of a feeding bottle with the air conduits, showing the rubber nipple drawn tion. Fig. 2 is a top plan view of the bottles neck. Fig. 3 is a section through the bottles neck on line AB of Fig. 1. Fig. 4 isa detail view of one of the conical shaped air conduits. Figs. 5 and 6 are sectional dei milk from the tail views on an enlarged scale of the air l conduits,-showing their relation to the bottles neck.

' The air conduits a in the neck I) of a bottle c are conically shaped and their apexes d cud a short distance before the mouth of the 1 bottle, forming with the same a small smooth margin 0, the rubber nipple f is drawn in the customary well known manner I over the bottles neck, covering the same to a. distance a trifle below the bases 6 of the 0011- ical air conduits, and'fitting tightly against the margin 0, thus preventing the escape of milk, while during the creation of a partial vacuum in the nipple by the suction and the air conduits and the bottles mouth, tobe engaged by a rubber nipple drawn over the full length" of said air conduits, for the purpose .of preventing the escape of milk and yet allowing-the entrance of air into, the

the purpose set forth.
